Don't really think there is any big PC game development companies left in Australia is there? Maybe Creative Assembly/Sega

Off the top of my head, I'd say the biggest ones left are SEGA Studios Australia in Brisbane, 2K Marin (formerly 2K Australia, formerly Irrational) in Canberra, KMM in Sydney, and EA's Firemonkeys in Melbourne. Though some of the other indies like Halfbrick might be bigger now than you think.

Yeah, but Firemonkeys aren't PC developers, don't think Halfbrick are either? I didn't know that 2k office in canberra still existed either, I thought it had disappeared, didn't realise it had been folded into 2k Marin.
